1. In a food processor using the chopping blade, process 3 cups of the peanuts along with the peanut oil and salt, until the mixture is smooth. Include the black pepper and cloves if you want a slightly spicy flavor.

2. Add the remaining 1 cup peanuts and process until they are finely chopped. (If you prefer smooth peanut butter to crunchy peanut butter, add all the peanuts at the beginning.) Crunchy Peanut Butter will keep, tightly covered, in the refrigerator for up to 2 months.
